通過iOS精靈從一個類到另一個

我有一個Spritekit項目在我的主屏幕上的xcode。不過，我真的想從另一個班級管理它，以便不會聚集我的主人。所以我添加了一個新類來管理和處理它。可悲的是，我似乎無法讓它顯示在我的主要（或者我可能做錯了）。我myscene.m由幾乎相同的代碼，包括飛船，這是我太感動了代碼（我沒有刻意添加方法，如touchesBegan）通過iOS精靈從一個類到另一個

// joysitck.m 
// controlpad 
// 


#import "joysitck.h" 


@implementation joysitck 
{ 
    BOOL controlButtonOn; 
} 
float controlx=200; 
float controly=200; 
float touchX = 0.0; 
float touchY=0.0; 


- (instancetype)init 
    { 
     if (self = [super init]) { 
      self.name = @"controlPadNode"; 

     SKSpriteNode *controlPadNode = [SKSpriteNode spriteNodeWithImageNamed:@"game-controller-frontb"]; 

     controlPadNode.position = CGPointMake(controlx,controly); 
     [controlPadNode setScale:0.5]; 
     controlPadNode.name = @"controlPadNode"; 
     controlPadNode.zPosition = 1.0; 

     [self addChild:controlPadNode]; 
    } 
    return self; 
} 



- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event 
{ 
    UITouch *touch = [touches anyObject]; 
    CGPoint location = [touch locationInNode:self]; 
    SKNode *node = [self nodeAtPoint:location]; 

    //if control pad touched 
    if ([node.name isEqualToString:@"controlPadNode"]) { 
     touchX = location.x; 
     touchY = location.y; 
     controlButtonOn= true; 
    } 
} 

//when touch moves 
- (void) touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { 

    UITouch *touch = [touches anyObject]; 
    CGPoint location = [touch locationInNode:self]; 
    SKNode *node = [self nodeAtPoint:location]; 

    //if control pad touched 
    if ([node.name isEqualToString:@"controlPadNode"]) { 
     touchX = location.x; 
     touchY = location.y; 
     controlButtonOn= true; 
    } 
} 

- (void) touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event { 

    UITouch *touch = [touches anyObject]; 
    CGPoint location = [touch locationInNode:self]; 
    SKNode *node = [self nodeAtPoint:location]; 

    //if control pad touched 
    if ([node.name isEqualToString:@"controlPadNode"]) { 
     controlButtonOn= false; 
    } 
} 

//update method 
-(void)update:(NSTimeInterval)currentTime { 

    if (controlButtonOn) { 

     //the control pad 
     SKNode *controlNode = [self childNodeWithName:@"controlPadNode"]; 
     SKNode *node = [self childNodeWithName:@"spaceShipNode"];  
     float angle = atan2f (touchY - controly, touchX - controlx) ; 
     SKAction *moveShip=[SKAction moveByX:6*cosf(angle) y:0 duration:0.005]; 
     [node runAction: moveShip]; 

    } 
}

搜索節點樹以獲得所需的節點：https://developer.apple.com/library/ios/documentation/ GraphicsAnimation/Conceptual/SpriteKit_PG/Nodes/Nodes.html＃// apple_ref/doc/uid/TP40013043-CH3-SW17 – LearnCocos2D

@ LearnCocos2D我添加了下面的代碼，也是我的主要場景，但是控制板沒有顯示。我錯過了什麼？ - （SKNode *）controlPadNode return {self childNodeWithName：@「controlPad」]; } –

你的問題是什麼？ –

你還沒有添加joystick節點到現場。

將此代碼添加到MyScene的initWithSize法（[self addship]前）：

joysitck *joysitckNode = [[joysitck alloc] init]; 
[self addChild:joysitckNode];

仍然看不到操縱桿，btw在你的第二行你的意思是joystickNode對嗎？我是否正確地在joystick.m中添加了操縱桿？ –

是的。什麼是「joysitck」類型？可能是「位置」有問題，試着玩不同的值 –

啊是的......它確實顯示，但它是位置。此外，所有的方法，如觸摸開始和更新，它們不應該在joystick.m文件中？遊戲杆顯示，但現在不移動飛船節點。（以m定義）。我在joystick.m中加入太空船作爲孩子嗎？ –
